     "    - Generally speaking, if you have a very small distance cutoff, compounds must be extremely similar (i.e. high Tanimoto score) in order to be grouped into one cluster. Therefore, with a small distance cutoff, you’ll get more clusters with fewer compounds per cluster. Vice versa is true.\n",

     "**Note:** This is an extremely general overview, in reality, the output greatly depends on both the size and diversity of the dataset being used. There is no “default” cutoff that is set in Datamol and instead, each user should set cutoffs according to their specific dataset and use case. \n",
